METHOD AND APPARATUS FOR WOUND CLOSURE WITH SEQUENTIAL TISSUE POSITIONING AND RETENTION

摘要

Apparatus and related methods for sequentially positioning and retaining opposing sides of a tissue wound. The apparatus includes a device body having a head portion for positioning between first and second sides of the wound, with the head portion defining first and second retention zones on opposed side of the head portion. The device body further includes first and second approximation arms. The device body further includes a trigger assembly defining three stages of operation. A first stage of operation positions the first approximation arm proximate the first retention zone. A second stage of operation positions the second approximation arm proximate the second retention zone with the first approximation arm remaining in approximation to the first retention zone. A third stage of operation advances a fastener into the first and second retention zones. In this manner, the apparatus sequentially positions the first and second sides with respect to the head portion.

1. A method for securing skin tissue with a fastener, comprising:
placing a head portion of a fastening device within a skin wound; positioning a first side of skin tissue between a first approximation arm and the head portion; retaining the first side of skin tissue between the first approximation arm and the head portion; positioning the second side of skin tissue between a second approximation arm and the head portion while the first side of skin tissue remains retained; retaining the second side of skin tissue between the second approximation arm and the head portion; delivering a fastener into the retained first and second sides of skin tissue.
